http://issues.apache.org/bugzilla/show_bug.cgi?id=39538 ------- Additional Comments From [EMAIL PROTECTED] 2006-05-15 16:34 ------- (In reply to comment #3) > Someone has already ported it. There's a sourceforge project > (http://collections15.sourceforge.net/) out there that does it. Yes, someone has attempted to port the commons.collections but the projects seems dead. The current source code has many coding errors. The programmers simply replaced the type <E> everywhere without forethought. That's wrong. There is a document named "generics-tutorial.pdf" available from sun.java.com website. It explains in great detail how parametized classes should be code. The project was done without good technical knowledge of Java 1.5 parametized classes. THE TYPICAL ERROR: class Set<E> { void add(E d) {...} // that's wrong!!! } - the method add should read void add(<? extends E> d) {...} // so any subclass of E is acceptable. I don't see much motivation to pursue commons.collections15 which is a shame. It's one of the most important Jakarta library! -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
